AppCleaner is an application which will easily allow you
to deinstall your applications. It is not enough to put an application
in the trash to remove it. Other small files are created by
the application and unnecessarily fill up your hard disk.
AppCleaner is able to find these small files and lets you remove your applications properly.

AppDelete is an application for Macs that will delete the application
you choose and any associated items (files and folders) that belong to
that application. Now you will no longer have to hunt through your
system to find these items and delete them manually. Or worse, just let
them sit on your Mac forever even though the application is long gone!

OK, here's a fairly simple idea: what if applications could be
uninstalled as easily as they are installed, in other words, by
drag-and-drop. Wait, I can already hear you say: "They can! By using x,
y or z!". Well, nice try, sunshine!
Neither x, y or z are truly that simple, right? What can be considered
the exact opposite of dragging an application to the Applications
folder? Opening another application, dragging the unwanted application
to that application, clicking a button, clicking another button,
quitting? Nope!
The exact opposite would have to be... dragging the application to the
trash. Ah, there you go! This is exactly what AppTrap does. Whenever you
drag an application to the trash, a dialog window will pop up, asking if
you want to delete the associated system files too. Simple as that.

It's a real-world test suite that assesses your computer's performace
capabilities. Maxon Cinebench is based on Maxon's award winning
animation software Cinema 4D, which is used extensively by studios and
production houses worldwide for 3D content creation. Maxon software has
been used in blockbuster movies such and Spiderman, Star Wars, The
Chronicles of Narnia and many more.
Maxon Cinebench runs several tests on your computer to measure the
performance of the main processor and the graphics card under real world
circumstances. The benchmark application makes use of up to 16 CPUs or
CPU cores and is available for Windows (32- and 64-Bit) and Macintosh
(PPC- and Intel-based).
The resulting values among different Operating Systems are 100%
comparable and therefore very useful with regard to purchasing
decision-making. It can also be used as a marketing tool for hardware
vendors or simply to compare hardware among colleagues or friends.

lost a partition. Combining several powerful scanning algorithms, Disk
Drill provides a complete Mac data recovery solution.
The demo will show you files that have been deleted. You'll need to pay the price to recover them.

DiskWarrior is the safest, the most technologically advanced, and the
most powerful utility to eliminate directory damage available for any
computer. DiskWarrior uses a different approach to disk directory repair
than other programs. DiskWarrior is not a disk repair program in the
conventional sense. Instead of patching the original directory, it uses
a patent-pending technology to quickly build a new replacement directory
using data recovered from the original directory, thereby recovering
files and folders that you thought were lost and that no other program
could recover.

Have you ever deleted images from your digital camera's memory card and needed them
afterwards? In spring 2003 I ran into that problem after processing some images using a
buggy shell script: About 35 of those files were gone and of course (remember Murphy's
Law) I had deleted the camera's memory card before ... I found out how to restore the
images using a hex-editor, but it turned out to be pretty tedious. This was the moment
when the idea for "Exif Untrasher" was born.

Geekbench is a cross-platform benchmark for macOS, Windows, and
Linux.
Geekbench tries to measure the performance an average application can
expect from the computer being benchmarked. As such, all of the
benchmarks in Geekbench are written in platform-neutral C and C++, and
have no platform-specific optimizations, and Geekbench is compiled with
what we consider the de-facto standard compiler for each platform, with
the compiler switches suggested by the compiler for release code.

GeekTool shows system logs, unix commands output, or images (i.e. from the
internet) on your desktop (or even in front of all windows).
Use File mode to monitor MacOS X activity with /var/tmp/console.log or
/var/log/system.log, or Shell mode to launch custom scripts or commands
like "df" to check space left on filesystems, "uptime" to monitor load
of your machine... FInally, Image mode helps you monitor bandwith usage,
CPU loads, memory availability of your server, via tools like MRTG or
RRD.

GrandPerspective is a small utility application for Mac OS X that graphically shows the
disk usage within a file system. It can help you to manage your disk, as you can easily
spot which files and folders take up the most space. It uses a so called tree map for
visualisation. Each file is shown as a rectangle with an area proportional to the file's
size. Files in the same folder appear together, but their placement is otherwise
arbitrary.

Hardware Monitor is an application to read out all available hardware
sensors in Macintosh computers. The program can display and visualize
measured values in a large variety of fashions. It can also store and
export readings. The application Temperature Monitor is available for
free, but is limited to accessing temperature sensors only. The
application Hardware Monitor is commercial shareware, but can access
additional sensors if your computer is equipped with them. This includes
the following sensor types:
Battery sensors on portable computers
Voltage sensors
Current (amperage) sensors
Fan speed sensors
Sensors for pulse-width controlled fans
Power and load sensors
Moreover, the applications can display additional technical information
about your computer. Among other information this includes:
Processor type
Processor and bus frequencies
Manufacturing information

Applications distribute several files throughout your system storage
devices. Deleting an application itself is mostly not enough and will
leave files untouched. iTrash uses a special search algorithm to find
all related files and deletes them when asked.

iStat menus lets you monitor your system right from the menubar.
Included are 8 menu extras that let you monitor every aspect of your
system.
CPU, Memory, Disks, Network, Temps, Fans, Bluetooth, Date & Time

Maintenance is a system maintenance and cleaning utility for macOS which
you can use to run miscellaneous tasks of system maintenance: run
periodic scripts, rebuild the databases, delete application, font, and
System caches, and more.

MenuMeters is a set of CPU, memory, disk, and network monitoring tools
for MacOS X. Although there are numerous other programs which do the
same thing, none had quite the feature set I was looking for. Most were
windows that sat in a corner or on the desktop, which are inevitably
obscured by document windows on a PowerBook's small screen. Those
monitors which used the menubar mostly used the NSStatusItem API, which
has the annoying tendency to totally reorder my menubar on every login.
The MenuMeters monitors are true SystemUIServer plugins (also known as
Menu Extras). This means they can be reordered using command-drag and
remember their positions in the menubar across logins and restarts.

- The CPU Meter can display system load both as a total percentage, or broken out
as user and system time.
- The Disk Activity Meter displays disk activity to local disks on the system
(anything that is a IOKit BlockStorage driver).
- The Memory Meter can display current memory usage as either a pie chart,
thermometer, history graph, or as used/free totals.
- The Net Meter can display network throughput as arrows, bytes per second, and/or
as a graph.

OmniDiskSweeper is a Mac OS X utility for quickly finding and deleting
big, useless files and thus making space on your hard disks.

Sloth is a program that displays a list of all open files in use by all
the applications your user account is running on the system -- this list
includes IP and Unix sockets, character devices and directories. This
list is presented along with the names of applications using the file
and their process IDs. Sloth thus makes it easy to find out which
applications are using which files. Includes support for list filtering,
process killing, sorting, timed updating and more.

Your Mac's hard drive, even if it is a Solid State Drive, is more likely
to experience problems than any other component on your Mac. Because
data changes so frequently, it can sometimes get scrambled. So, it's
important to be able to test drives for problems and then repair them.
Sadly, if something is physically wrong with the drive, it will need to
be backed up and replaced, but the sooner this type of damage is
detected, the fewer files - like cherished memories and important
personal documents - will be lost. Most drive problems, however, result
from data being in the wrong place, and can be repaired using TechTool
Pro’s Volume Rebuild tool.

High Sierra and initial APFS compatibility: Apple is redefining how Macs
use their disks. APFS, or Apple File System, is their new path forward.
If you have upgraded, or plan to upgrade, to macOS High Sierra and have
a solid state drive, your disk is going to get 'upgraded' to APFS. Be
ready for APFS and macOS High Sierra with TechTool Pro 9.6 - it is the
first third party Mac utility to offer APFS compatibility. And it has
been fully tested to support High Sierra (macOS 10.13) as well. One
extra upside to APFS drives: you don't need to start up from an eDrive
to test them.
Trust us when we say that there is a lot going on with this new file
system, so this is just *initial* support. Techtool Pro can now test and
repair these disks, even eDrives on them, but we're still hard at work
exploring the depths of this file system. Some more advanced features
will be coming down the road.

XRG is an open source system monitor for Mac OS X. XRG allows you to
monitor CPU activity, GPU activity, memory usage, battery status,
machine temperature, network activity, disk I/O, current weather, and
stock market data. The goal of XRG is to be a functional system monitor
that has a clean and flexible interface, so it doesn't intrude on the
rest of your Mac experience.
